Orthogonal phase-frequency coded signal in a pulse against interrupted sampling repeater jamming
Interrupted sampling repeater jamming (ISRJ) uses the under sampling technology to transmit and repeat the radar intercepted signals. As a new kind of coherent interference, it is widely used in self-defence interference. At the same time, the existing radar anti-jamming technology cannot effectivel...

description |
Interrupted sampling repeater jamming (ISRJ) uses the under sampling technology to transmit and repeat the radar intercepted signals. As a new kind of coherent interference, it is widely used in self-defence interference. At the same time, the existing radar anti-jamming technology cannot effectively combat it. In this study, the principle of ISRJ is analysed. In view of the mismatch between the jamming signal and the radar transmitting signal, an orthogonal phase-frequency coded signal in a pulse is designed. In signal processing, matching and filtering are processed separately through each sub-signal. The simulation results show that the designed signal has a good inhibitory effect on ISRJ. |
